Greece lies in a highly seismically-active region. The vast majority of earthquakes cause no damage or injuries, however.
The country is located in a complex geological boundary zone in the eastern Mediterranean between the African and Eurasian Plates.
The northern part of Greece lies on the Eurasian Plate while the southern part lies on the Aegean Sea Plate.
The Aegean Sea Plate is moving southwestward with respect to the Eurasian Plate at about thirty millimeters (one inch) per year while the African Plate is subducting northward beneath the Aegean Sea Plate at a rate of about forty millimeters (1.6 inches) per year.
